Abstract

The present invention provides a three-dimensional display device, which can display a 3D image of higher quality than a conventional one by arranging a parallax barrier layer with higher positioning accuracy, and a method for fabricating such a display device. The three-dimensional display device 100 includes a first substrate 11, which is provided closer to the viewer and which is made of a transparent material, a second substrate 21 arranged so as to face the first substrate 11, a liquid crystal layer 30 provided between the first substrate 11 and the second substrate 21, and a parallax barrier layer 12 provided on the surface of the first substrate so as to face the viewer. A polarizer 40 is further provided on the surface of the viewer-side substrate 10 that includes the parallax barrier layer 12 thereon.
